Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
808764-35-4 1-Acetyl-3(5)-trifluoromethyl-4-nitro-5(3)-(phenyl)pyrazole MFCD00153638 (CAS 808764-35-4), molecular formula C12H8F3N3O3 and molecular weight 299.21 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 808764-35-4 1-Acetyl-3(5)-trifluoromethyl-4-nitro-5(3)-(phenyl)pyrazole MFCD00153638 (C12H8F3N3O3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures 808764-35-4 1-Acetyl-3(5)-trifluoromethyl-4-nitro-5(3)-(phenyl)pyrazole MFCD00153638 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
